I agree completely, with an Overclocked system and over clocked gfx card the PSU becomes one of the most important parts of the system. At stock speed I would say a good quality 800w minimum PSU. Heavily over clocked system a 1000w good quality PSU should be aimed for. Any failures by low rated PSU’s could take out your hardware and fry it.
Never skimp on the PSU it’s most important!
A few years ago I was running a pre-built Hewlett Packard PC which originally had a dual core Athlon II, no discreet graphics card & a little 300watt psu, I added a quad core Phenom II & an Asus 5570 (no additional power cables required), A few months later I went to a local computer repair shop and bought a new cheap brand 750 watt psu, soon after I ordered an Asus GTX 560ti online, When it came I fitted it and it seemed fine, a couple of days later I paused a game I was playing and went to make a cuppa, when I got back the PC was shutdown & when I tried to boot up it was completely dead, Later testing showed that both the PSU and brand new GTX 560ti were dead.
It's one of those it won't happen to me scenario's that sometimes does happen and considering the price of a VII it's definitely not a risk I'd be willing to take.
